When the galvanized steel is painted, how can we avoid the coating falling off?

 

In the actual construction process, many customers in the galvanized steel since the painting, often produce the phenomenon of paint layer off, today, we around this phenomenon, discuss together, "galvanized steel how to paint, in order to avoid the paint layer off".

 

First of all, the surface properties of galvanized steel have changed after being treated by galvanized process. Because the zinc layer is smooth, most of the paint can not adhere to it, which is easy to fall off and can not play the role of anti-corrosion protection.

Therefore, although galvanized has certain anti-corrosion effect, but in harsh environment, it is necessary to use paint coating.

 

Galvanized steel spraying paint, should choose special epoxy primer, this paint is dedicated to galvanized substrate coating, has very good adhesion, ensure that the paint film does not fall off, excellent anti-corrosion.

 

Special epoxy primer main features:

1, can be used for galvanized iron plate, stainless steel, aluminum plate, cast iron, carbon steel and other substrates, adhesion to, do not fall off, do not drop paint

 

2. The substrate is free from grinding without sandblasting, saving labor and material costs. The solvent can be used to scrub the surface to remove the oil

 

3, salt spray resistance time up to 1000h, excellent corrosion resistance

 

4, can match fluorocarbon, polyurethane, epoxy and other finish paint

 

5, the paint has solvent and water-based environmental protection

 

In the case of coating galvanized steel, there are no special requirements, the normal brush or spraying process can be used.
